DESCRIPTIVE LIST OF FLOWERS. 139 



BROWALLIA. BLUE AMETHYST. 



[Named by Linnaeas, in honor of John Browallius.] 



Browallia data* A tender annual from Peru. It 

 grows one and a half foot high, and bears an abundance 

 of small brilliant blue flowers, from July to September. 

 There is also a variety with white flowers. 



To have it in perfection, it should be sown in hot-beds, 

 and transplanted into the border in June. The plants 

 are quite minute when they first make their appearance, 

 and unless protected from the sun, are liable to be 

 destroyed. The same be said of nearly all plants with 

 very fine seed. In the open ground, about the middle of 

 May, is a suitable time for planting. 



CALANDRINIA. 



[Named after Calami rini, a German botanist.] 



Calandrinia grandiflora. Great-flowering. This is a 

 half-hardy annual ; grows two feet high ; blooms from 

 June to October. It is a fine plant for growing in mas- 

 ses. When the fine, rosy lilac flowers of this very beau- 

 tiful plant are fully expanded, being produced in vast 

 profusion, and continuing for so long time in bloom, they 

 make a pleasing appearance, and never fail to give ample 

 satisfaction. To have it in its greatest perfection,the seed 

 should be planted in pots, and placed in a hot-bed early 

 in the spring. In June the plants should be turned into 

 the ground. The soil should be a rich sandy loam. 



C. discolor is in habit very much like the other; the 

 foliage is purple on the under side ; it requires the same 

 treatment. C. Burridgii, G. speciosa, and C. umbellata, 

 are all handsome species or varieties, but rather delicate, 

 and not perhaps desirable except in extensive collections.
